ITR-Nature of Employment for State Government Aided School Teachers & Exemption U/S 10(10A) for CVP

With regard to filing ITRs for State Government Aided School Teachers it would be great if someone could throw light on the related queries:-

A) While filing ITR what should be selected under Nature of Employment for State Government Aided School Teachers?

1) Others OR 2) State Government

B) When the state government aided school teachers receives retirement benefits with regard to Commuted Value of Pension Exemption U/S 10 (10A) the nature of employment becomes extremely important as

1) For Government Employees - Commuted Value of Pension fully exempt

2) For Other Employees - 1/3 or 1/2 of Commuted Value of Pension exempt

I am assuming that if I file the return as 'Others' - CPC Processing Unit will flag the return 'if full exemption is availed U/S 10 (10A)' - Please guide
